COMBINED GASOLENEv BLOWPIPE AND BURNER.

. SPECIFICATION forming part of Letters Patent No. 596,536, dated January 4, 1898.

Application filed J1me 29,1897.

To all whom it may concern:

Be it known that I, MORTIMER C. PARK, of Platte City, Platte county, Missouri, have invented certain new and useful Improvements in a Combined Gasolene Blowpipe and Burner, of which the following is a full, clear, and eX- act description, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to combined gasolene blowpipes and burners; and my object is to produce a device of this character whereby a most intense heat may be generated at a minimum of cost and a flame produced which is under perfect control, as regards its volume and formation, of the operator.

A further object is to produce a device of this character which is simple, durable, and cheap of manufacture.

With these objects in view the invention consists in certain novel and peculiar features of construction and combinations of parts, as will be hereinafter described and claimed.

In order that the invention may be fully understood, I will proceed to describe it with reference to the accompanying drawings, in which- Figure 1 represents a top plan view of a combined blowpipe and burner embodying my invention. Fig. 2 represents a vertical cross-section of the same. Fig. 3 represents a horizontal section of the fuel-reservoir in an inverted position. Fig. 4 represents, on an enlarged scale, detail perspective views of parts of the burner. Fig. 5 represents, on the same scale, a longitudinal section of the burner.

In said drawings, 1 designates a reservoir or tank, preferably of cylindrical form and mounted upon an enlarged base 2, said base preferably forming the bottom of the tank also. Communicating with the tank at its upper end is a filling-tube 3, and closing the same is a removable cap 4, which may be screwed thereon or otherwise secured. The top plate and base-plate of the reservoir or tank are tied together, preferably, by means of vertical rods 5, engaged at their upper ends by clamping-nuts 6. Projecting vertically upward from and communicating with the reservoir is a tube or pipe 7, and the passage of said pipe is controlled by an ordinary gas-burner valve 8, provided with a thumbpiece or handle 9.

Serial No- 642,8'73. (No model.)

A burner 10 of the type shown or of any other preferred construction is mounted upon said tube or pipe, though, if preferred, (and it undoubtedly will be desirable in some connections,) I may connect said burner or its equivalent with the tube 7 by means of a flexible tube, (not shown,) a bent metal tube, or a folding tube or arm, so as to dispose the burner at a point more remote from the tank. I have found in practice, however, that there is not the slightest danger involved in disposing the burner in the position shown.

11 designates a pipe which extends down into the reservoir and terminates in a coil or air-distributer of many convolutions, as at 12. Said air-distributer is located in a horizontal plane, preferably, and very near the bottom of the reservoir and is provided in its under side with a large number of perforations 13, from which the air must escape vertically upward, and consequently permeate the entire body of the liquid, so as to give the device a high generating power or large gas-generating capacity in proportion to its size. The air as it rises to the surface of the gasolene, which is the oil preferably used, is completely saturated and occupies the chamber formed above the surface of said oil-viz. thevaporchamber. The opposite end of the pipe 11 is connected to an air-supply (not shown) through the medium of the flexible tube 14, and mounted upon said pipe 11 and supported, preferably, by an extension of the top plate is a valve 15, provided with a handle 16 of the type shown or any other preferred type.

To withdraw the gases from the tank, I employ a pipe 17, which projects downward only a slight distance through the top of the reservoir. The valve 18 is mounted upon said pipe and is provided with a handle 19.

Connecting the pipes 11 and 17 outward of the valves 15 and 18, respectively, is a crosspipe 20, provided with a valve 21, having a handle 22, and connected to the outer end of the pipe 17 is a flexible tube 23, which carries at its outer end a burner of my improved construction. This burner comprises a short pipe 24, which diminishes toward its discharge end to form a nozzle 25 and at such end is externally screw-threaded to receive a disk 26, forming, preferably, the front closed end of a cylinder 27, the rear end of which is also closed. Said cylinder 27, a-t'its rear end, is

preferably screwedu-pon the pipe 24, as-shown at 28, and within said cylinder said pipe 24is provided with one or more perforations 29, for I a purpose which will be presently explained.

cylinder 27 is a cap 31, provided at its end with an opening 32, in diameter less than the cylinder 27 or the circular series of slots or said burner;

openings formed therein. This cap is adj ustable upon the cylinder in order to equalize the escape of gas from the periphery or outer circle with that escaping from the central tube or pipe, as it will not burn properly without its proper adjustment. A vertically-adjustable rod 35 is provided at its upperenlcfl with an angle-arm terminating in a ring 36, in

which a soldering-receptacle 37 is remov- 10. By this means, owing to the fact that the receptacle'37 has an opening in its bottom, the flame quickly reduces the solder if it is ametalwhich flows easily. If a harder metal, such as .gold, it will be necessary to employ the other burner also, and then he opens valve 18 andignites the gasas it escapes from Thegas escapes from the noz- 21c 25 in a thin direct, but invisible, stream and also through the surrounding circle of slotsor openings 31 from the cylinder 27, to which it has access through the opening or openings 29. As such gas escapes through said circle of openings it is deflected down-I wardly and inwardly toward the central stream, escaping fromthe nozzle by reason of the fact that the opening '32 is of smaller diameter than the circle of slots or openings 30. To control the combustion at the burner, the valve 21 is provided, and under the proper manipulation of the lever 22 the fiameescaping from said burner, and which of course is.

conical in form, may be tapered or elongated more or less. The more air that is permitted to pass through the pipe 20 the more attenuated or pointed the conical flame becomes, and the heat is intensified in a corresponding degree. The greater volume of air from the reservoir does not unduly discharge the gas,

' because the pressure of air takinga cross-cut through the pipe 20 backs the gas and thereby equalizes the pressure. In other Words, the burner performs its function properly and consumes the entire volume of inflammable vapor or gas escaping therefrom irrespective of the pressure of the air-supply,

the burner would not operate.

owing to the fact that as the pressure of the ainsupply is increased the valve 21 will be opened-wider and the air passing'through the cross-pipe, as explained, tends to resist the discharge through the pipe 17, and consequently equalizes the pressure of the gas. It will be noted in this connection that without the opening or openings in the pipe 24 and the outlet of the gas or vapor which passes through said openings into the cylinder 27 In fact,when the 'gas is discharged from the nozzle25 alone the-flame of a lighted match held at such point isinstantlyextinguished; but when the air escapes also in a uniform volume externally of the nozzle .a perfect combustion takes place, and the flame, as hereinbeforestated, .may be intensified by its proper regulation; but if. the amount of air passing through the .crosspipe by means of valve 21 be increased beyond the proper amount necessary to make the hottest flame it will prevent a sufficient quantity of vapor escaping from the reservoir and stop combustion. The necessary amount of air is regulated by the temperature of the room or place where the burner is located to some extent.

This burner is designed particularly for dentists who .practice in small towns not provided with gas-works or in the country and who have heretofore been at a disadvantage in economically and expeditiously performing work which requires intense heat.

From the above description it will be apparent that'I have produceda combined gasolene blowpipe and burner which embodies the featuresof advantage enumerated in the statement of invention, and it is to be understood that I reserve the right to make such changes as practical experience may dictate which are not a departure from the spirit and scope of the invention.
